Results: Among the 497 retrieved articles, we identified 2 cross-sectional and 9 prospective studies comprising a total of 339,692 individuals with 18,228 AF events. The highest category of coffee consumption (greater than or equal to 5 cups/day) was not associated with increased or decreased risk of AF (pooled RR, 0.98; 95% CI: 0.88-1.09; p less than 0.001; I2 = 59.21%), compared to the lowest category (1 cup/day).
Conclusions: We found no evidence that coffee consumption is associated with increased risk of AF.
Thank goodness that someone found something not associated with an increased risk of AF.
